R connect to HANA with ODBC

hi All.

      These days I want to use R to connect to hana with RODBC like the following guide

      http://scn.sap.com/community/hana-in-memory/blog/2012/02/21/sap-hana-my-experiences-on-using-sap-hana-with-r

       I installed the RODBC package , and I can connect to the Data Source with odbcConnect

         But each time I submit a query , there will be an error saying that ""S1000 362 [SAP AG][LIBODBCHDB DLL][HDBODBC] General error;362 invalid schema name".

        The Schema is really exists, What is the problem .

        Thank you for help.
